Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlation-driven Kondo effect. On a superconductor, bound states emerge inside the ...
NATURE PORTFOLIO2023Phenomenological theory of variational quantum ground-state preparation
Ivano Tavernelli, Giuseppe Carleo
The variational approach is a cornerstone of computational physics, considering both conventional and quantum computing computational platforms. The variational quantum eigensolver algorithm aims to prepare the ground state of a Hamiltonian exploiting para ...
College Pk2023Square and rhombic lattices of magnetic skyrmions in a centrosymmetric binary compound
Magnetic skyrmions are topologically stable swirling spin textures with particle-like character, and have been intensively studied as a candidate of high-density information bit. While magnetic skyrmions were originally discovered in noncentrosymmetric sys ...
2022Tunneling processes through magnetic impurities on superconducting surfaces: Yu-Shiba-Rusinov states and the Josephson effect
Magnetic impurities generate a wealth of phenomena on surfaces. On metals, conducting electrons screen the magnetic moment giving rise to the Kondo effect. On superconductors, the Yu-Shiba-Rusinov (YSR) states emerge inside the superconducting gap due to t ...
EPFL2021Resonant Inelastic X-ray Scattering Studies of Low-Dimensional and Frustrated 3d Transition-Metal Oxides
3d transition-metal oxide materials with strong electron correlations and low dimensionality give rise to emerging exotic phases. Resonant inelastic X-ray scattering (RIXS) has developed as a powerful spectroscopic tool for probing the collective excitatio ...
EPFL2021Disorder‐Induced Signal Filtering with Topological Metamaterials
Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad
Disorder, ubiquitously present in realistic structures, is generally thought to disturb the performance of analog wave devices, as it often causes strong multiple scattering effects that largely arrest wave transportation. Contrary to this general view, he ...
2020Kondo lattice excitation observed using resonant inelastic x-ray scattering at the YbM5 edge
Marco Grioni, Thorsten Schmitt, Marco Guarise
We present a study of the resonant inelastic scattering response of YbInCu4 excited at the tender YbM5 x-ray edge. In the high-temperature, paramagnetic phase, we observe a multiplet structure which can be understood at an ionic level. Upon cooling through ...
AMER PHYSICAL SOC2018Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator
Jan Hugo Dil, Joël Mesot, Stefan Peter Muff, Kazimierz Conder
Topological Kondo insulators have been proposed as a new class of topological insulators in which non-trivial surface states reside in the bulk Kondo band gap at low temperature due to strong spin-orbit coupling. In contrast to other three-dimensional topo ...
